ANCHOR FOR SAFETY-BELTS.

Specification of Letters Patent.

Patented May 14., 1912.

Application filed August 17, 1911. Serial No. 644,704.

To all whom 2'2, may concern:

Be it known that I, WILLIAM A. CHERRY, Jr, a citizen of the UnitedStates, residing at WVhite Plains, VVestchester county, New York, haveinvented certain new and useful Improvements in Anchors forSafety-Belts, of which the following is a full, clear, and exactdescription.

My invention relates to improvements in anchors for safety belts such asare worn by window cleaners.

In the cleaning of windows in tall buildings it is customary for thoseemployed in such hazardous work to be provided with a safety belt, theends of which are attached to suitable anchoring devices such asscreweyes, secured at the side of the window casing, so that in theevent the window cleaner falls, he will be supported by the belt thusanchored. By reason of the importance of the duty performed by suchanchoring devices, it is of obviously vital importance that such devicesbe made in the best possible manner, and secured in such a way as toprevent all possibility of accident.

To that end it is my aim to provide an anchor adapted for brickbuildings, and which shall be so anchored in the brick work surroundingthe window opening as to prevent all possibility of accidentaldetachment. Incidentally other advantages will be apparent to any onefamiliar with devices of this character from a reading of the followingdescription and an examination of the accompanying drawings, in whichIhave shown my invention in the preferred form.

Figure 1 is a plan view representing one layer of brick with myanchoring device thereon. Fig. 2 is a bottom plan view of the anchoringdevice.

1 represents the head of the anchoring device, the same being preferablyin the form of a capstan, as distinguished from an ordinary eye. It isaround the narrow part of this capstan that a. strong snap hook orterminal, such as safety belts are provided with, is secured. At thebase of the shank is a broad flange 2, which extends up and down theface of the wall. The wall as shown is formed of brick, three bricksbeing indicated at 3, 4 and 5.

6 is the main arm of the anchor, which is flat and which preferably iswidest at that end connected to the flanged anchor head 1. This main arm2 is provided with an offset or hook 7 at its rear end. The overalllength between the inner shoulder of the hook 7 and the inner shoulderof the flange 2 corresponds to the length of the brick employed, so thatwhen in place the hook 7 will rest between the two bricks 3t, which arearranged end to end.

8 is an arm extending laterally from the main arm 6. 9 is an ofiset orhook at the end of said arm. This hook extends preferably in a directionopposite to the direction of the hook 7 10 is a hook or o-ifset in thesame plane as the hook 9, but below the arm 8. The hooks 9 and 10, whenthe anchoring device is in place, are arranged to stand between twobricks arranged side by side. 11 is a rearwardly directed perforated earin the same plane with the hooks 9-10.

12 is a hook-like extension, which is preferably secured to the car 11by an eye 13,

so that it may partake of a swinging or adjustable movement' 14; is thehooked end of the extension 12. This part 12 is preferably made fromspring steel wire of suficiently heavy gage to pre vent bending,excepting under extraordinary strains greater than this particulardevice could be subjected to in this connection. The hooked end 14: isswung into the space to one side of the brick 5. hen the parts are inthis position, as indicated in Fig. 1, another layer of brick is appliedwith the usual cement. It will now be seen that when the cement ishardened, the anchoring device will be held rigidly by not less thanthree bricks, namely, the brick 3, the brick above the brick and thebrick directly above the brick. 3.

15 is a brace extending diagonally from the end of the arm 8 to the baseof the arm 6 adjacent to the flange 2.

It is obvious that the structure is reversible and may be applied to thebrick work ateither side of a window opening. It is also obvious thatthe arrangement is such that the lines of strain, in the event ofemergency, are resisted in a most efiective manner. It is also obviousthat, inasmuch as the part 12 is hinged to the main body, its end may beconveniently adjusted to any position where in it may be anchoredbetween the brick, which is a feature of importance, because in someinstances brick of irregular size may be employed, so far as the sameare hidden from view. Another advantage in connecting the member 12 tothe main body so that itmay swing, is found in the fact that the devicesmay be more compactly packed and shipped, and there is materially lessdanger of breakage.

While I have shown my invention in its preferred form, I appreciate thatvarious modifications may be made without depart ing from the spirit andscope of the invention.

hat I claim is:

1. In an anchor for window cleaners safety belts, an anchorage headhaving a flanged base, a fiat arm extending rearwardl from said base andhaving a hook arrange transversely thereof at its rear end, another armextending laterally from the first mentioned arm and having a hook atthe end thereof transverse thereto and a brace running obliquely fromthe last mentioned arm to the base of the first mentioned arm near saidflange.

2. In an anchor for window cleaners safety belts, an anchorage headhaving a flanged base, a flat arm extending rearwardly from said baseand having a hook arranged transversely thereof at its rear end, anotherarm extending laterally from the first mentioned arm and having a hookat the end thereof transverse thereto and a brace running obliquely fromthe last mentioned arm to the base of the first mentioned arm near saidflange, said hooks aforesaid extending in opposite directions relativelyto the plane of the arms and brace.

3. In an anchor for window cleaners safety belts, an anchorage headhaving a flanged base, a flat arm extending rearwardly from said baseand having a hook at its rear end, another arm extending laterally fromthe first mentioned arm and having a laterally extending hook at itsend, a brace running obliquely from the last mentioned arm to the baseof the first mentioned arm near said flange, and a swinging hookextension carried by the laterally extending arm.

4. In an anchor device for window cleaners safety belts, an anchor head,a flange at the base thereof, a rearwardly extending arm having a hook,a space between said flange and said hook corresponding with the overalllength ofthe brick, a laterally extending arm projecting from said firstmentioned arm at a point intermediate its length, a hook at the end ofthe laterally extending arm arranged to overstand the edge of the samebrick, a swinging extension having a hook end, said extension beingconnected to the laterally extending arm and of a length sufiicient tooverstand the edge of an adjacent brick and to stand in a line obliqueto the line of the first mentioned arm, and a brace connecting the endof said laterally extending arm with the first mentioned arm near saidflange and lying in substantially the same or a parallel line with theswinging hooked extension.
